The completion of the human genome sequencing project represented a major milestone in the field of biological and medical sciences. It happened about ten years ago in the framework of the US project Human Genome. It has been the results of years of expensive research activity. At that (recent) time, although the importance of that result was clear, the possibility of handling the human genome as a commodity was far from imagination due to cost and complexity of sequencing and analyzing complex genomes.Today the situation is very much different, since the order of magnitude of the cost necessary for sequencing a human genome is rapidly reducing.
